Hello every one
I want to log data in .txt file in sd card with Arduino due board. I use SD library for this but I can't save any file in sd card ... and then I found SdFat library ... again I can't run with sample codes
my sd card module is : Buy MICRO SD CARD MODULE TF CARD MEMORY SHIELD - SD STORAGE ...
I format my sd card as FAT16
I connect sd module pins to ICSP header
please help
this appears to be the schematic of your SD module.
This module has a 5V to 3.3V converter, (chip TXB0104), for the SD card.
The arduino Due provides 3.3V at the pin output, so it may not work with this module.
What voltage are you feeding this SD module?

Thanks for reply
I feed 5V to sd card module vcc pin
How Can I Config SD.h library for Arduino Due ?
Hi @mettiblack72
The problem doesn't seem to be one of library.
It appears to be voltage levels.
The output levels of the DUE pins are 3.3V and your module asks for 5V on the input pins.

Hi @ruilviana
I removed IC and then solder pins straight to SD socket , again I couldn't run sd.
All Voltage are 3.3v
